' FOR THE SUPPLY OF OZONE AND THE LIKE Application filed July 10, 1930,Serial No. 466,947, and in France April 14, 1930.

' The present invention relates to an installation for the supply ofozone for industrial, domestic, medical and other use, for instanceamongst others for beauty, dental and mouth treatments and biologicalstudies.

The installation comprises pipes connected to a device in which ozone isproduced and a compressor apparatus of any kind, to convey the ozonewhere required and at a desired to pressure.

1 In order that the invention'may be better understood, it will now bedescribed with reference to the accompanying drawings in Fig. 1 shows inelevation an apparatus according to the invention, suitable for fixingon a wall or the like.

. Fig. 2 shows a section in side elevation, to

alarger scale, of a portion of the apparatus shown in Fig. 1, the actualozone-producing part being indicated in dotted lines.

7 Fig. 3 is a view in elevation partly in sectionof the ozone-producingdevice indicated in Fig. 2.

Fig. 4 is a plan view of one of the suppogting discs of theozone-producing device, an

Fig. 5 shows in elevation a portable apparatus, constructed according tothe invention and mounted on wheels.

The ozone-producing apparatus comprises a receptacle A carried bybracket-like devices B and adapted'to be hermetically closed by L. Thecover has a central orifice provided coil D and means of a cover J fixedin position by bolts the current and these are connected to the outputterminals of a Ruhmkorfi coil D.

The actual ozone-producing device, which is adapted to be housed in thereceptacle A,

is constituted by an aluminium disc I forming the positive pole andconnected electrically to one of the threaded rods D by means of a stripor laminated contact and by a second disc I also of aluminium connectedto the lower threaded rod D and forming the negative pole. These discsare interconnected by an ebonite rod or spindle H and each is piercedwith eight holes 0 in which are mounted glass tubes M.

Each glass tube M is surrounded by a helie0 I cally coiled aluminiumwire N which contacts with the upper disc I whilst the interior of eachtube has located therein a twisted flattened strip onwire N of copper oraluminium which contacts with the lower disc I.

The device thus constituted is introduced into the receptacle A, ahandle or the like V formed with two branches facilitating itsinsertion.

- When a difference of potential is established between the armaturesthus formed by connecting them to the poles of a Ruhmkorff after acertain quantity of air under pressure has been introduced into thereceptacle A, then this air is ozonized at .the end of a determinedperiod of time.

Piping connected to the orifice F allows the ozonized air to be broughtto any desired place and at the required pressure, which may beregulated at will.

Accordingto Fig. 1,the receptacle A is mounted on a board by suitableconnecting means. The Ruhmkorff coils D and D" are provided connected tothe actual ozonizing device represented in Fig. 3. I is the switch and Ethe middle portion of a passage for the ozone from the receptacle A to adis: tributor F, provided with hree or more cocks G for the distributionof ozonized air. The 9 I a of example only.

cocks G are adapted to be connected to pipes leading to positions inwhich the ozone is to be utilized. A glass receptacle B may be employedfor the sterilization of water by the ozone.

The wall apparatus just described is described for dental or medicalservice with the object of using the ozonized air as a disinfectant andantiseptic medium.

Fig. 5 shows a complete apparatus constructed according to the inventionmounted upon a trolley and especially suitable for use in a hospital orthe like. In this method of carrying the invention into eifect, 1represents a receiver or reservoir for compressed 'air mounted uponcasters. The compressed air is supplied by a small piston compressor 2operated by an electric motor 3. @n a table or support 4 fixed to thecover of the reservoir 1 the receptacle A is mounted, the interior or"the receptacle having therein the ozone-producing device shown in Fig.3. Piping 5, with cocks 6 and 7, allows the ozonized air to'be broughtinto a receptacle 8 filled with water by means of a plunger tube 9 fixedin the cover 11, so as to bubble through the water in the receptacle toassure its perfeet sterilization. A cock 10 is provided for drawing ofi'the water thus sterilized. The cover 11 forms at the same time adistributor for ozonized air and with this object is provided with twolateral cocks 12 which are adapted to be connected to rubber pipes orthe like for conveying the ozonized air to the desired positions.

The methods of carrying the invention into effect particularly describedare given by way The compressed air may be supplied by means of a smallcompressor and the apparatus described would then be connected to thereceiver of the compressor or even could be located of if desired.

The present, invention is further applicable to all cases for the supplyof ozone or ozonized air under pressure, whatever the precise form ofthe actual ozone-producing apparatus and can be utilized as a wallapparatus as has been hereinbefiore described or coupled with any fixedor movable suitable compressor apparatus.

What I claim and desire tors Patent of the United is:-

1. An apparatus for producing and supplying ozone or ozonized air formedical,

to secure by Let- States of America dental and other purposes,comprising a receptacle with one open end, a cover for said open end,means for clamping the cover in position over the opencnd to secure anhermetic seal, supporting means for said receptacle, an insulatedelectrical conductor passing from the exterior to the interior ofthereceptacle, another insulated electrical conductor pass ing from theexterior to the interior of the rein the interior there-- said aluminiumdiscs, a plurality of apertures in each of said aluminium discs for thereception of the plurality of glass tubes, 8. helically coiled aluminiumwire surrounding each of said tubes, and electrically connected'to oneof the aluminium discs. a twisted strip of copper in each of the saidtubes and electrically connected to the other of the said aluminiumdiscs, an inlet for compressed air to the interior of the receptacle, anoutletfor ozone or ozonized air from the receptacle, a piping system inconnection with the saidoutlet, a plunger tube in connection with saidpiping system, and a receptacle for liquid into which the said plungertube is adapted to projdct from above, for the purposes set forth.

2. An apparatus for producing and supplying ozone or ozonized air formedical, dental and other purposes, comprising a receptacle with oneopen end, a cover for said open end, means for clamping the cover inposition over the open end to secure an hermetic seal, supporting meansfor said receptacle, an insulated electrical ing from the exterior tothe interior of the receptacle, another insulated electrical conductorpassing from the exterior to the interior of the receptacle and spacedfrom the first-mentioned insulated electrical conductor, a Ruhmkorfi'coil carried by the said supporting means, connections between theoutput terminals of the Ruhmkorfi' coil and the 1 two said electricalconductors, a plurality of glass tubes located in the receptacle, a discof aluminium adapted to be located in the receptacle-and to beelectrically connected to one of the electrical conductors, anothersimilar disc of aluminium adapted to be located in the receptacle andelectrically connected to the other conductor, a spacing rod of eboniteconnecting the two said aluminium discs, a plurality of a ertures ineach of said aluminium discs for t e reception of the plurality of glasstubes, a helicallg coiled aluminium wire surrounding each 0 said tubesand electrically connected to one of the aluminium discs, a twistedstrip of copper in each of the said tubes and electrically connected tothe other of the said aluminium discs, a reservoir for compressed air,supporting wheels to the said reservoir, the said reservolr carrying themeans supporting the open-ended receptacle conductor passand associatedarts, a compressor carried by the reservoir or supplying compressed air"plunger tube is adapted to project from above, for the purposes setforth.
